Synopsis: Important: kernel security and bug fix update
Advisory ID: RHSA-2007:0169-01
Advisory URL: https://rhn.redhat.com/errata/RHSA-2007-0169.html
Issue date: 2007-04-30

Product: Red Hat Enterprise Linux
CVE Names: CVE-2007-0771 CVE-2007-1000 CVE-2007-1388
- - ---------------------------------------------------------------------
1. Summary:
Updated kernel packages that fix security issues and bugs in the Red Hat
Enterprise Linux 5 kernel are now available.
This update has been rated as having important security impact by the Red
Hat Security Response Team.
2. Relevant releases/architectures:
Red Hat Enterprise Linux Desktop (v. 5 client) - i386, noarch, x86_64
RHEL Desktop Workstation (v. 5 client) - i386, x86_64
Red Hat Enterprise Linux (v. 5 server) - i386, ia64, noarch, ppc, s390x, x86_64
3. Problem description:
The Linux kernel handles the basic functions of the operating system.
These new kernel packages contain fixes for the following security issues:
* a flaw in the IPv6 socket option handling that allowed a local user to
read arbitrary kernel memory (CVE-2007-1000, Important).
* a flaw in the IPv6 socket option handling that allowed a local user to
cause a denial of service (CVE-2007-1388, Important).
* a flaw in the utrace support that allowed a local user to cause a denial
of service (CVE-2007-0771, Important).
In addition to the security issues described above, a fix for a memory leak
in the audit subsystem and a fix for a data corruption bug on s390 systems
have been included.
Red Hat Enterprise Linux 5 users are advised to upgrade to these erratum
packages, which are not vulnerable to these issues.
4. Solution:
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
This update is available via Red Hat Network. Details on how to use
the Red Hat Network to apply this update are available at
